The code use onclick() to call a method that can remove an array list dynamically when you set the index position of an array as a parameter in the deleteList(). You can apply this script to your code to make your transaction faster, it is a user-friendly program feel free to modify it.

We will use JavaScript to add some new feature to the website interface by actually written into an HTML page. It is what gives your page a different interactive elements and animation that engage a user.
